Wasps of the Genus Tachytes. 29 
9. Eyes separated on the vertex by a distance equal to 
the length of the third joint of the flagellum. Clypeus 
broadly subtruncate at the apex ; vertex with sparse distinct 
punctures; second joint of the flagellum distinctly longer 
than the third. Pygidial area subtriangular, rather broadly 
rounded at the apex, clothed with dark reddish pubescence, 
which changes to fuscous in some lights. Second sternite 
shining deeply and sparsely punctured, with a smooth tri- 
angular area in the middle of the apical margin. Third 
abscissa of the radius longer than the second by about one- 
quarter, equal to the distance between the recurrent nervures 
on the cubitus. Basal joint of fore tarsus with six spines. 
6. Eyes separated on the vertex by a distance equal to 
the length of the first joint of the flagellum; antennz 
rather stout, the third to sixth joints of the flagellum feebly 
arcuate beneath. Scutellum rather more distinctly punc- 
tured than the mesonotum ; seventh tergite subtriangular, 
rather narrowly truncate at the apex, clothed with red gold 
pubescence. Eighth sternite truncate at the apex, the angles 
not produced. 
Hab. Meru lowlands, Ngare na Nyuki (Sjéstedt), Novem- 
ber, 2; Nyasaland, Mlanje (S. A. Neave), February, 2; 
S.E. shore of Lake Nyasa between Ft. Maguire and Ft. 
Johnston (S. A. Neave), March, 2. 
My description is taken from a pair from Nyasaland, 
which I think belong to Cameron’s species, but I have not 
examined the type. 
33. Tuchytes associata, sp. n. 
¢. Niger; tegulis, femoribus apice, tibiis tarsisque ferrugineis ; 
fronte clypeoque aureo-pilosis; thorace segmentoque mediano 
dense et pallide fulvo-pilosis, mesonoto lateribus aureo-pubes- 
cente, segmentis dorsalibus 1-5 apice fascia argenteo-pubescente ; 
area pygidiali pallide aureo-pubescente ; alis pallidissime fulyo- 
hyalinis, nervis testaceis. 
Long. 15 mm. 
3. Near testaceinerva, Cam., but the clypeus is very 
narrowly depressed on the apical margin, the depressed 
portion slightly porrect and with a-distinct angle in the 
middle ; vertex not,distinctly punctured ; eyes separated on 
the vertex by a distance equal to the length of the second 
joint of the flagellum; basal joint of fore tarsi with five 
spines; second ventral segment finely and evenly punctured, 
subopaque, not shining with sparse large punctures on the 
apical half asin ¢estaceinerva ; seventh tergite broad, truncate
